To aZlzljhom t may concern:

Be 1t known thatA we, JOSEPH E. LEONARD i and GEORGE H. ILTEN, citizens ofthe United States,l residing at Cedar Rapids, in the 5 county of Linn and State of Iowa, have invented certain new and useful Improvev ments inOvens; and we do vhereby declare the following to be a full, clear-,land'exact .description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

-This invention relates toy stoves and' ranges, and more particularly to the con-- struction of the oven therefor.

The Object /of the Iinvention is to improve the oven and facilitate the assembling of the parts thereof' by a novel construction ofthe face-plate and side-platesjand the comicotions therefor, whereby the face-plate may be securely attached tothe side-plates by a bolt at each corner, thereby dispensing with a great many bolts which were formerly re-V quired:

The-invention is fully disclosed in the description and claims following, reference be ing had to the accompanying drawings, in which-.-

Figure l is afrontelevation of an oven embodying our invention. Fig. 2 is a section of one corner of the same in the line a b of Figs. l, 3 and 4.', Fig. 3 is a top view of the corner clamping plate. Fig. 4; 4is a bottom view of one corner of the front-plate.

Fig. 5 is a view in perspective of acorner of one of the side-plates.

,In the drawing, l denotes an elevated oven communicating by a flue 2 with. the combustion chamber of a stove below, not shown. lThe oven is provided with doubled walls 3 and 4 at the sides, bottom and top, the space between the walls being for the products of combustion to pass around the Vinner in closure and thus heat the oven, 1n a manner .that need not be particularly described.

-good many'bolts, while inthe former case the rods were exposed to the destructive heat fromy the combustion chamber.

The improved device for'connecting the front and side-plateswill now be'described, The front plate .5, as will be' seen, is provided with channels 7 and 8 to receive the edges of the side-plates 3 and 4, respectively.

Between them, at each corner, are bolt-holes 9 to receive stove-bolts lO. Thew'hole front oven is folded at an angle, as Vshown at 8 in '.Figs.2 and 5, these folds being made before the sheets are bent at the corners. The angle of the J`old'conforms to that of thechannelint'o-which it is to tit, a perfectly tight joint being secured by the useV of stoveputty, in va well known way. Bridging the space between the channels 7 and` 8 at the corners are clamp-plates 11,having angled terminals 12` and 13 .fitting nicely intothe angles of the side-plates, respectively. These clamp-plates Vhave holesf coinciding lwithA those in the corners of the front-plate, to'

receive stove-bolts, and on the under (inner) side have lugs 14 to hold thefnuts 15 from turning.. In assembling the oven, itis in position on top, and the clamp-plates, with nuts in position, are successively placed in position, there being holes (not shown) in the outer side-plates to admit the operators hand, -and the bolts inserted and screwed tight. The front-plate is thus securely and tightly held in place, and at the expenditure of little time and eHort.

Having thus described our invention, we'v claim:

l. The combination with the front and `edge of each side-plate entirely around the 'placed on its back, the 'ront plate 5 is laid side-plates of anoven, of a clamp-plate clonnectin'g the inner and outer side-plates, and a bolt connecting said front-plate and clamp-plate.

2. The combination with the front and angled side-plates of an oven, of a clampplate bridging the space between the inner and outer sideplates, and conforming to their respectivelangl'es at the corner, a connection of each end of the clamp-plate with its respective side-plate corner, anda member connecting the clamp and front-plates.

3. The combination of a front-plate for an oven, channeled for inner and outer side plates, side-plates folded 4on the front edges to conform with the said channels, clampplates with angledl ends tting the angles of said -folded edges, and a member connecting the same with the front-plate.

4. A connection for the front and sideplates of an oven, comprising a' front-plate 5 channeled for inner and outer side-plates,

ing said clamp and frontplatos at the corners.'
